Objective: Pneumomediastinum and pneumopericardium are rare occurrences in young athletes, but they can result in potentially life-threatening consequences.Background: While involved in a rugby match, an 11-year-old boy received a chest compression by 3 players during a tackle. He continued to play, but 2 hours later, he developed sharp retrosternal chest pain. A chest radiograph and an echocardiograph at the nearest emergency department showed pneumopericardium and pneumomediastinum.Differential Diagnosis: Sternal and rib contusions, rib fractures, heartburn, acute asthma exacerbation, pneumomediastinum, pneumopericardium, pneumothorax, traumatic tracheal rupture, myocardial infarction, and costochondritis (Tietze syndrome).Treatment: Acetaminophen for pain control. Uniqueness: To our knowledge, this is the only case in the international literature of the simultaneous occurrence of pneumomediastinum and pneumopericardium in a child as a consequence of blunt chest trauma during a rugby match.Conclusions: Pneumomediastinum and pneumopericardium may be consequences of rugby blunt chest trauma. Symptoms can appear 1 to 2 hours later, and the conditions may result in serious complications. Immediate admission to the emergency department is required.

The role of infectious agents in children with recurrent/chronic lower respiratory disorders (R/CLRDs) is not clear, whereas it has been largely studied in acute respiratory diseases. The purpose of the study was to evaluate the frequency of infections, in particular viral infections, in children with R/CLRDs correlating their presence with clinical/biohumoral parameters. Eighty children affected by R/CLRDs underwent bronchoscopy and analysis of bronchoalveolar lavage (BAL) for cells, mediators (eosinophil cationic protein-ECP, interleukin-IL-8, tumor necrosis factor-TNFα) and pathogens (viruses and bacteria). Viral genomes were detected in 50/80 (62.5%) children. Rhinovirus, the principal detected virus (26/50, 52%), occurred more frequently in male children. Higher percentages of BAL neutrophils and IL-8 values were detected in virus positive than negative children. ECP values resulted significantly higher in the children with rhinovirus than in those with other viruses. No other statistically significant correlation between viral findings and clinical/biohumoral data were found. Respiratory viruses, especially rhinovirus, seem to play an important role in children with R/CLRDs. They are associated with changes in BAL cellularity and inflammatory cytokines. Further studies are needed to confirm the persistence of viruses in these patients and to identify eventual therapeutic strategies.

Flexible bronchoscopy (FOB) with bronchoalveolar lavage (BAL) is useful in children with recurrent pneumonia to discriminate among different aetiologies. Fever post-FOB and BAL has reported in these children but its origin is subject to debate. METHODS: We examined risk factors associated with fever in immunocompetent children with recurrent pneumonia undergoing FOB with BAL. Before the procedure all children performed routine blood tests, total and specific IgE dosages, Chest X-ray. All BAL specimens were tested for total and differential cell counts, interleukin (IL-8), eosinophil cationic protein (ECP), tumor necrosis factor (TNF), bacterial growth and respiratory viruses (reverse transcription-polymerase chain reaction). The cutoff for fever was 38°C in the 12 hours after the procedure.
